I'd guess Honda has enough money to run whatever they like just about anywhere they like.
I remember another F1 competitor invading a bastion of American Hot Rodding about 40 years ago.
The tone of the various comments, in print and on TV, were surprisingly similar to what I'm seeing here.
That raises a question; how many Offy powered, front engined roadsters do you see at the Indy 500 these days?
There is no substitute for cubic dollars, and, with a $10,000,000.00 racing budget, I think they'll probably spend whatever it takes to achieve their goal, whatever it is.
